Lugworm

Slicing, material experiments, and machine control in Grasshopper.

Named after the lugworm (German: Wattwurm), which casts coiled strings of sand that look like extruded layers.

Lugworm is a Rhino 8 plugin for clay and cementitious-material 3D printing. It was developed at the Institute of Digital and Autonomous Construction (IDAC), Hamburg University of Technology, for liquid deposition modelling (LDM) in a laboratory setting.

You can find the food4rhino instance here: food4rhino. The open source code will be published after additional testing.

Safety

Lugworm generates toolpaths and can connect to Duet machines. Review every G-code file and robot program in Robot Simulation before running it. Keep the emergency stop within reach and stay with a running print.

The drawn robot models are approximate. Read the reach, joint-limit, and speed checks as well as inspecting the preview. Machine-state and board-identity checks block control actions when they fail.

No warranty

Machine control has been tested only on our own machine. Treat any other machine as untested. To collaborate on making a machine compatible, see About.
